SPECIFICATION fornuing part of' Letters IE'atent No. 519,696, dated May 15,1894.

' Application filed November 10. 1893. Serial No. 490,569. (No model.)

To all whom it may concern:

Be it known that I, THOMAS PATRICK CAR BOLL, of Franklin Furnace, county of Sussex, State of New Jersey, have invented certain new and useful Improvements in Car-Couple's, of which the following is a specification, reference being had to the accompanying drawings.

The Object of my invention is to produce improved mechanism for elevating the drawhead of couplings to suit dierent heights of Q cars.

In the accompanyin-g drawings: Figure 1' is a side elevation of a draw-bar, with the draw head in the lowered position. Fig..2 is a similar view, with the drawhead in the elevated position. Fig. 3 is a side elevation of the draw-head separated from the draw-bar. Fig. 4: is a top plan view of the draw-bar with the draW-head detached;

Referring to the figures on the drawings: l indicates a draw-bar adapted to be carried in suitable bearings 2 on the bottom of the car and having a spring buffer. 3, as illustrated.

4 indicates a box open at the top and front and adapted to carry a closely fitting drawhead 5. The box is preferably made integral with the end of the draw-bar, as illustrated.

6 indicates a concussion plate which extends from the bottom of the box to the height to which the draw-head may be elevated. It is adapted to receive the shock from an approaching coupler and to distribute it through the draw-bar to the spring as well when the draw-head is elevated as when it is depressed and in line with the draw-bar.

6* indicates graduated apertures in opposite sides of the box and 7 indicates guide pins projecting from the bottom of the draw-head and adapted to pass through apertures 8 in the bottom of the box.

9 indicates notches in the pins and 10 transverse grooves in the bottom of the draw-he'ad. Pins 11 are designed to be inserted through oneof these setsof apertures, across the grooves 10 and through the notches in the pins. By

' selecting the higher or lower apertures 7 the elevation of the draw-head may be controlled. The pins are preferably provided with heads 12 and hinged ends 13, which, being bent down after the pins are inserted, serve as convenient means for fastening them in place. The

sides of the draw-head are preferably pro-' vided with vertical guide ribs 14,`that move in recesses 15 in the sides of the box.

16 indicates a screw screwing into the bot- `tom of the box and having a Wheel 17 by which it may be conveniently operated in raising and lowering the draw-head for adjustment within the'box. Side ledges 18 are preferably provided upon the upper sides of the drawhead, designed to protect the junctions between the draw-head and the box. The drawhead is designed of course to receive 'one end of a link 18 the other end of which is adapted to fit within the drawhead of another car. The link is provided with notches 19 adjacent to its ends which are engaged respectively by a vertically movable plate or pin 19 actuated to engage or disengage the notch by a spring actuated hooked lever 20 pivotally carried upon bearings 21. It will be readily understood how two cars furnished with similar drawheads may be coupled by their engagement with the link, the vertical adjustment of the drawheads acconmodating them and pins adapted to enter into the apertures and the notches, substantially as and for the purposes specified.

4. The combination with a draw-bar and box, a vertically movable draw-head, mechanism for securely adjusting the elevations of the draw-head, and a screw in ,the bottom of the box adapted to raise and lower the drawhead, substantially as and for the purposes specified.

5. The conbination with a draw-bar, box

and graduated apertures in the sides thereof, box, a pin adapted to fasten the draw-head in of a draW-head and notched guide pin, a pin its adjustnent, and a. screw for controlling adapted to be inserted through the apertures the elevation of the draW-head within the box, in the sides of the box, and having a. hinged substantiaily as and for the purpose specified;

5 end, substantiaily as set forth. In testimony of all which I have hereunto 15 6. The combination with a draw-bar and subscribed my name. box, of a. draw-head, notohed guide pins on THOMAS PATRICK CARROLL. the bottom thereof, graduated apertures in Witnesses: I the sides of the box, guide ribs on the sides JOHN P. HENDERSHOT, IO of the draw-head, recesses in the sides of the DAWSON WOODRUFF.
